Abstract (en)
[origin: EP3785873A1] A process for recycling thermoplastic polymer material to produce polymer pre-form, the process comprising the steps of:(i) pre-treating a polymer material for example by separating, sorting, cleaning and/or shaping;(ii) shredding the pre-treated polymer to produce polymer flakes;(iii) processing the polymer material to produce a pre-form, characterised in that prior to the step (iii) of producing the pre-form, the polymer flakes are compacted to form pellets.
